"That'd be an awful career decision, darling." West points his Colt 1860 Army in a prostitute's face as she is reaching for her john's pistol hanging off the bedpost. Note the "JW" on the handle.

Colt 1861 Navy

When West fires his sidearm into the roof of the White House to convince a disguised Gordon that he is impersonating the President, the gun is the subtly different Colt 1861 Navy.

West fires his sidearm into the ceiling. This is actually a Colt Blackpowder Signature Series 1861 .36 Navy converted to .38 by Kenny Howell. Two guns were sent and converted, they were later sold at the Stembridge Auction - Regards, Tecolote

Colt 1862 Police (with Richards-Mason conversion)

When an impertinent and not-too-sharp Pinkerton detective reaches for Captain West's main sidearm, West speedily draws his backup gun, a Colt 1862 Police with Richards-Mason conversion and nickel finish.

"That'll get you killed." West draws his back up Colt Police.

Colt Single Action Army Cavalry

General McGrath (Ted Levine) carries a Single Action Army as his main sidearm. He uses it to casually gut-shoot an irate patron at Fat-Can's brothel, and threatens Dr. Arliss Loveless (Kenneth Branagh) with it as his men are slaughtered.

Colt Theur Derringer

Artemus Gordon (Kevin Kline), despite his professed dislike for firearms, keeps a single-shot Colt Theur Derringer on a spring-loaded catch inside a belt buckle. West later slips it to him in Loveless's hideout, and Gordon conceals it on his wrist spring (appears to be a modified holdout device). The pistol is actually a modern reproduction known as the 4th Model Derringer, as opposed to the time period appropriate 3rd Model derringer and can be distinguished by its smaller .22 bore rather than the .41 bore of the original pistol.

Single barrel shotgun

An assassin hiding in a painting uses it to try to kill West, but fails to.

Winchester Model 1873

West removes a cut-down "Mare's Leg" style Winchester Model 1873 from the arms cache in The Wanderer and cocks it one-handed as he and Gordon ride to confront Loveless.

This is the screen-used Winchester 1873 cut-down "Mare's Leg" as seen on the panel wall in the film.

West cocks the Winchester Model 1873 one-handed. (You can tell it's a '73 rifle rather than an '87 shotgun because of a number of identifiers, the most noticeable of which are the shape of the receiver and the brass loading block seen from the bottom.)

The other panel has some "steampunk" weapons, most of which are actual 19th century weapons (or custom, non-firing replicas) fixed up to look that way. Some of the guns are in their original configuration, but others are heavily modified which makes them difficult to identify.

Remington 1858 "Cattleman's Carbine"

A Remington 1858 New Army "Cattleman's Carbine" is seen in the cabinet aboard The Wanderer, and Amazonia (Frederique Van Der Wal) also carries one (equipped with a telescopic sight) aboard the Tarantula, before she is ordered at gunpoint to toss it over the side.

Wheelchair Gun(s)

For self-defense, Dr. Arliss Loveless's (Kenneth Branagh) wheelchair is equipped with twin barrels at the front of the left arm and rear of the right arm, to deliver twin loads of double-aught buckshot. He uses the rear-facing guns to kill General McGrath (Ted Levine), and attempts to use the front-facing guns to shoot West.
